Development of a Coal Resource Database in the Iowa Natural Resources Geographic Information System for Monroe County, IA, October 1990

摘要

The Iowa Department of Natural Resources (IDNR) decided in 1988 to institute a computerized natural resource data system based on a GIS. PcARC!INFO was selected to manage vector (line) data and EPPL7 was selected for raster data. The evaluation of remaining resources in fourudcoal beds in Monroe County, reported herein, was one of the first projects undertaken. The project was selected because it was small, could be clearly defined, and would yield comparable and verifiable results. Further, it was expected to require development of some basic data files required by DNR for the Natural Resources GeographicudInformation System (NRGIS). Finally, much of the preliminary work of collecting, interpreting, andudorganizing the data had already been completed.
